Novak Djokovic and Kei Nishikori have advanced to the third round of the Madrid Open following their wins on Wednesday.
The Serb was made to work hard for his victory over an inspired Nicolas Almagro, winning 6-1, 4-6, 7-5 after over two hours of thrilling tennis on the Manolo Santana court.
The second seed looked to be on course for a routine win in after cruising through the opening set in just 26 minutes.
But Almagro was more aggressive in the second set, forcing Djokovic to save a number of break points before he eventually earned the breakthrough in the final game to clinch the set.

The Spaniard took the momentum into the decider where he went 3-0 up and Djokovic looked on the verge of another early exit.
But this time, the world number two put up the defences as he has done so often in the past and simply refused to miss, wearing Almagro down until he broke back twice to earn the victory.
Elsewhere, sixth seed Kei Nishikori came from a set down to beat Diego Schwartzman 1-6, 6-0, 6-4 in a touch over two hours. Schwartzman would save no less than four match points in the final set before the Japanese superstar earned one last break to reach the third round.

Nishikori faces David Ferrer next after tenth seed Jo-Wilfried Tsonga pulled out without a ball being served due to injury.
Fifth seed Milos Raonic powered past Luxembourg's Gilles Muller 6-4, 6-4 without so much as facing a break point.
Finally, rising Australian star Nick Kyrgios made short work of Ryan Harrison, needing just 58 minutes to defeat the American 6-3, 6-3 to put him on course to face Rafael Nadal.
